A higher up at my company recently derisively said one of the major reasons people didn't want to return to office was because they saved money working from home... as if that's a ridiculous reason. Some of these executives are so out of touch with their inflated salaries.
Yet the same douchebag will cut costs in the company at every turn. And is probably cheap as fuck in personal budgeting. These people need to fuck right the hell off.
I think this is what people mean when they say "people don't work as hard from home" are talking about. Having a little extra spending money makes you not worry as much about appeasing your boss.
It really means the bosses can't preside over a culture of fear quite so well if people aren't cowering outside their offices seeking their attention. They like to be the centre of attention and work being done remotely makes them feel just as meaningless as the rank and file workers.
People are more productive at home. We know this. It works and has worked. These companies that refuse to acknowledge it will continue to destroy themselves.
Companies that adapt to remote work will have access to better workers who can afford to be choosey about jobs. And since remote workers concentrate better and work longer hours they're even more productive.
Companies which force workers to come into the office will languish and become less profitable and they won't even know why.
